To all whom it'may concern:

Be it known that 1, ROBERT G. WILSON, a subject of the King of GreatBritain, and a resident of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Bracketsfor Use in Constructing Concrete lValls, of which the following is aspecification.

My invention relates to devices or apparatus for use in concreteconstruction work and more particularly relates to means for retainingand positioning the side plates or members of a mold into the spacebetween which the concrete is introduced to form a Wall or similar part.

My invention is particularly useful in constructing concrete green-housebenches of the monolithic type wherein it is desired to provide thebench with side walls rising vertically from the bed or platform of thebench. In such cases if it is desired to have straight walls of eventhickness and smooth finish, the concrete must be molded between longside plates forming the sides of the mold and means provided forpositively retaining or preventing these side plates from spreading orgetting out of proper position. It is only possible to mount or supportthe means for retaining or holding the side plates on the outside of thebench or on but one side of the mold but it is essential that means beprovided for both plates for holding them in their position or at leastfor preventing them from separating beyond a predetermined amount. Myinvention contemplates the use of a bracket or device for this purposewhich is entirely separate from the side plates and which is capable ofbeing mounted on a fixed support on but one side of the mold and adaptedto engage both side plates thereof.

One of the objects of my invention is to provide means whereby theopposite side plates of a mold may be positively retained in place and awall of uniform thickness attained in such cases where it is possible toonly mount or support the retaining means on one side of the mold orstructure to be formed between the said side plates.

Another object of my invention is to provide simple and positivelyacting means whereby the same bracket or retaining means may be used fordifi'erent thicknesses of wall it may be desired to form in the mold.

By my invention a number of the brackets are placed along the side ofthe bench on which it is desired to form the side wall and the arms ofthe bracket set for the desired thickness of wall. The side plates ofthe mold are placed between the arms of the brackets and the cementfilled in between the plates until the plates are forced out as far asthey will go against the arms of the brackets which limit the thicknessof the wall. The brackets are so formed that the usual spreader forforcing the cement down solid in the mold and the finishing tool forgiving a smooth or special shaped top to the wall may be employedwithout removing the brackets.

It will be understood that my invention is not limited to use inconstructing greenhouse benches, but it might be employed for variousother uses without departing from the spirit thereof.

The invention consists in the novel devices, combination of parts anddetails of construction hereinafter more particularly described and thenspecified in the claim.

In the accompanying drawings, Figure 1 is a general transverse sectionand partial elevation of a monolithic green-house bench during thecourse of construction and having my invention applied thereto. Fig. 2is a general side elevation of the same. Fig. 8 is a detached elevationof a bracket constructed in accordance with my invention. Fig. 4 is anedge view of the same. Fig. 5 is a plan view of the bracket.

In the drawings I show my invention as applied for use in constructing agreenhouse bench of the general type shown and described in prior patentto John Wilson No. 889,319, dated June 2nd, 1908, as it is for this usethat my invention in its preferred form is most particularly useful,although it will be understood that the invention is not in any waylimited to use in this connection.

The bed or top of the bench 1 is formed in any desired way and isprovided with supports 2 as is usual.

8 and 41 indicate parallel plates rising vertically from the bed or top1 at either side thereof and forming the side members of a mold betweenwhich the sides or walls 5 of the bench are formed.

At intervals throughout the length of the bench, string-pieces 6,arranged in pairs are suitably supported below the bed 1 and in adirection transverse to that in which the walls 5 are to be formed,eachstring-piece of any pair being spaced a suitable distance from itscompanion piece and the ends thereof projecting for a. greater .or. lessdistance beyond the sides of the bed 1. The string 1 pieces 6 arepreferably placed one either side of the bench supports or legs 2 andrest on ledges 15 formed on the sides of said sup ports. Bolts 16passing transversely through the string-pieces clamp the same to thesupports in an obvious manner.

The inner plate or member 3 of the mold is,- preferably provided-with aflange which rests upon the top of the bed 1, while the outer plate 1which is somewhat longer. preferably rests upon the string-pieces 6, theup per edge of each plate being preferably provided with a flangeprojectinglaterally in opposite directions. 7 indicates posts suitablysupported at intervals along the wall or side to be formed and in thepresent embodiment are supported in the projecting ends of thestringpieces 6. The posts might be secured in any desired way to thestring-pieces but are preferably positively held thereto by means of asuitable bolt 8 passing through the base flange?) of the post 7 andthrough aplate 10 adapted to engage each string-piece of a pair-and spanthe space between them. The post is clamped to thestring-pieces bytightening up on a suitable wing-nut or-other means whereby the baseflange 9 of the post and the plate'10 are squeezed up on either side ofthe string-pieces. By loosening the wing-nut the position of the post 7may be adjusted or varied as desired.

The upper part of the post 7 is preferably provided with a laterallyprojecting arm provided with guides 11 within which a tongue 12 of adepending arm 13 works. The lower part of the post 7 is so formed thatthe outer plate 4 will rest against it, a suitable ledge beingpreferably provided as a seat for the upper flange of the plate.

The depending arm 13 engages the inner plate or side member 3 of themold at its lower end and forms a stop or abutment which limits theoutward movement of the plate and supports it against lateraldisplacement, a suitable ledge being provided .eral inverted U-shapeandthe concrete or v side member of the moldand provided with on thisarm for the flange on the upper edge whereby the distance between thearms may be variedand thereby walls of greater or less thickness moldedbetween them.

It will be noted that the bracket takes a genother material with whichit isdesirecl to form the wall is inserted between theside plates 3,

1 and forced down until the space between themhas been solidly filled,there being suflicient space between the upper part of the wall and thebracket for inserting the usual spreaderrfor this purpose. After themold has been filled up, the finishing tool is run along ontop of the uper flanges of the plates 3, 1 andunder the 00p of the bracket and theWall finished off, after which the brackets and other parts are removed.

.17 indicates a. groove formed in the inner or plate-engaging side ofthe post? and arm 13 below the ledges upon which the upper flanges ofthe side plates 5 and 4: rest. These grooves form a depository for theupper flanges. of side plates of less height than those shown and whichare preferably used when constructing lower walls or sides.

WhatI claim .as .my invention is:

In adevice of the character described, the combination of a postprovided with a flange at its base forming an adjustable support andadapted to form a stop for a side 85 member of a mold, an arm projectinglaterallyfrom the upper part of said post and provided with longitudinalguides and a clepending armf forming a stop for the opposite a lateralarmhaving a-slot whereby said arm is-adjustably secured to said post insaid guides, the upper part of the post and the depending arm beingoi'iset to provide an increased space between them above the partsforming the stops for the mold.
